We build custom ADUs for homeowners who want long-term value, rental income, or additional living space — not temporary solutions.

What Los Angeles Homeowners Say
FAQ – ADU Construction Los Angeles
How hard is it to get an ADU permit in Los Angeles?
Getting an ADU permit in Los Angeles can be complicated because plans must meet LADBS requirements, zoning rules, and California building codes. Many homeowners experience delays due to incorrect drawings or missing engineering details. Working with an experienced design-build contractor like DevArt8 Builders helps speed up approval because we prepare plans according to Los Angeles standards from the start.
How much does it cost to build an ADU in Los Angeles in 2026?
The cost of building an ADU in Los Angeles depends on size, site conditions, design, and structural requirements. Garage conversions usually cost less, while detached or hillside ADUs cost more due to foundation and engineering work. A detailed estimate requires property evaluation, zoning review, and design planning, which is why DevArt8 provides custom quotes instead of generic pricing.
What is the difference between garage conversion and detached ADU?
A garage conversion uses an existing structure, which usually makes it faster and less expensive. A detached ADU is built from the ground up and allows more flexibility in layout and size. The best option depends on the property, budget, and long-term goals.
Do I need structural engineering for ADU construction in Los Angeles?
Yes, most ADU projects require structural calculations, especially for detached units, hillside properties, or second-story structures. Los Angeles building department requires engineered plans to ensure safety. DevArt8 works with engineers to make sure every ADU meets code requirements.
How long does ADU construction take in Los Angeles?
Permit approval may take several weeks depending on the project, and construction usually takes a few months after approval. Projects with complex grading, hillside work, or custom design may take longer. A proper design-build process helps reduce delays.
Why choose a design-build ADU contractor instead of separate architect and builder?
Using one design-build contractor reduces miscommunication, speeds up permits, and keeps the project on budget. DevArt8 handles planning, engineering, permits, and construction in one system, which makes the process easier for homeowners.
Can DevArt8 handle Los Angeles hillside ADU projects?
Detached ADUs usually provide the highest rental value because they offer privacy and full living space. However, garage conversions and attached ADUs can also generate income depending on the location and size.
